Review on 🌡️ Enhanced Fluid Control Thermostat Kit by Derale 15719 by Will Randles

The addendum says it comes with brass fittings, it comes with 1/2" NPT to 1/2" plastic BARB. I will not be using plastic fittings on my 4L80E gearbox. I have about $3,000 and I refuse to use plastic hardware. I ordered brass fittings. Some people think cool liquid is the best way. The transmission oil has to be warm and some even do without the standard cooler and the transmission runs cold. Gears should work 200° without any problems. I use it on my 1997 GMC Sonoma and don't want the drivetrain to be too harsh. Some people think the cooler the better, but I'm not one of them.
